A research team from the University of Massachusetts Amherst has created an electronic microsystem that can intelligently respond to information inputs without any external energy input, much like a self-autonomous living organism. The microsystem is constructed from a novel type of electronics that can process ultralow electronic signals and incorporates a device that can generate electricity “out of thin air” from the ambient environment.

The groundbreaking research was published June 7 in the journal Nature Communications.

The discovery could have important implications for the health of aging brains and development of therapies for neurodegenerative diseases. Recent studies suggest that new brain cells are being formed every day in response to injury, physical exercise, and mental stimulation...

Scientists have demonstrated that conolidine, a natural painkiller derived from the pinwheel flower and traditionally used in Chinese medicine, interacts with the newly identified opioid receptor ACKR3/ CXCR7 that regulates opioid peptides naturally produced in the brain. The researchers also developed a synthetic analogue of conolidine, RTI-5152-12, which displays an even greater activity on the receptor.

These findings, which were published on June 3rd in the international journal Signal Transduction and Targeted Therapy (Nature publishing group), further advance the understanding of pain regulation and open alternative therapeutic avenues for the treatment of chronic pain.

Opioid peptides are small proteins that mediate pain relief and emotions, in...
